Where will the coldest temperatures hit as polar vortex brings Arctic air to US?

A severe cold wave, triggered by a displaced polar vortex, is set to bring dangerously low temperatures and strong winds to the U.S. starting February 6. The Midwest, Mid-Atlantic, and Northeast will face life-threatening conditions, with wind chills dropping to minus 30F in some regions.

A severe cold wave fueled by a displaced polar vortex is set to impact the United States starting February 6, with dangerously low temperatures and strong winds creating life-threatening conditions in multiple regions. The Midwest, Mid-Atlantic, and Northeast are expected to experience the harshest conditions throughout the weekend, according to forecasters.

Expected Conditions

The incoming Arctic air from Canada will combine with wind gusts reaching up to 60 mph. AccuWeather reported that temperatures in major urban areas such as Detroit, New York City, and Boston could drop into single digits. Gusty winds will make it feel even colder, with perceived temperatures significantly lower than actual readings. AccuWeather Chief Meteorologist Jonathan Porter stated, "The Arctic air combined with gusty winds could make it feel colder than any other point so far this winter."

Warnings and Advisories

By the morning of February 6, over 43 million Americans were under extreme cold warnings. Millions more were placed under winter weather advisories and high wind advisories.

Regions Most Affected

The coldest conditions are expected in the interior Northeast and New England. The National Weather Service (NWS) forecasts wind chills as low as minus 30 degrees Fahrenheit, posing serious risks of hypothermia and frostbite for anyone exposed to the cold outdoors.

Forecast for Major Cities

• Boston: Wind chills could reach as low as minus 30 overnight on February 7.
• New York City: Wind chills between minus 15 and minus 25 the night of February 7.
• Detroit: Wind chills ranging from minus 10 to minus 20 overnight February 6-7.
• Washington, D.C./Baltimore: Wind chills between minus 5 and minus 10 on February 7.

High temperatures on February 7 are expected to remain extremely low, staying in the single digits, teens, and low 20s. Interior parts of New England and the Northeast could experience wind chills in the minus 30s, while coastal areas may see wind chills ranging from below zero to the minus teens on February 7 and 8.

Snowfall Expectations

The NWS predicts light to moderate snow showers spreading from the Great Lakes into the Northeast and Appalachians starting February 6. Snow accumulation is expected to be between 1 and 3 inches in most areas, with coastal New England potentially receiving 4 to 5 inches on February 7.

Polar Vortex Explanation

The polar vortex is a large area of cold air in the upper atmosphere that typically rotates above the North Pole. Its position influences how far south Arctic air can move into the United States. This week, a weakened polar vortex has allowed a surge of Arctic air to penetrate the U.S. and other parts of the globe.

Safety Recommendations

The National Oceanic and Atmospheric Administration (NOAA) issued guidance for staying safe during extreme cold conditions:

• Maintain a cold-weather survival kit when traveling.
• Limit outdoor activity and cover exposed skin.
• Ensure pets and livestock are adequately protected.
• Prevent frozen pipes and avoid walking on ice of uncertain thickness.

Summary

The United States is facing a significant Arctic outbreak due to a disrupted polar vortex. Extremely low temperatures, strong winds, and snow are expected to impact millions of people from the Midwest to the Northeast. Authorities and meteorologists are urging residents to prepare for life-threatening cold and follow recommended safety precautions over the weekend.
